3. 3 2013: HL-LHC: from Design Study to Construction Project (funded) LRossi@TechMeet VAC - CERN 6March2014 c) Europe’s top priority should be the exploitation of the full potential of the LHC, including the high-luminosity upgrade of the machine and detectors with a view to collecting ten times more data than in the initial design, by around 2030. This upgrade programme will also provide further exciting opportunities for the study of flavour physics and the quark-gluon plasma. Update of 2013 Approved at special CERN Council Held in Brussels 30 May 2013 Update of 2013 Approved at special CERN Council Held in Brussels 30 May 2013

4. 4 Review of LHC & Injector Upgrade Program (CERN-MAC) LRossi@TechMeet VAC - CERN 6March2014 Recommendation (R1): The committee supports the full LHC high luminosity program (HL-LHC), including the full LHC Injector Upgrade (LIU) project and the Upgrade Scenarios 1 and 2, and recommends scheduling LS3 for the installation of all necessary equipment for the HL-LHC as early as possible to maximize the integrated luminosity of the LHC. Flull plan (incl. CC and LRBBW): OK
